This invention v'relates to a new and uset'ul the other side thei'eof, by Way of the rail way.

A. feature of the invention is the provision ot a plurality of tubular rollers having cast iron plugs in their ends, which plugs 1nelude steel journal pins, which are mounted lit) in bearings of the frame ofthe cattle guard. A further feature ol the invention is the provision of Wear plates for the joui-nal pins. The invention comprises further features a'ndwombination ot parts, as hereinafter set `t'orth, shown in the drawings and Claimed. in the drawings: Figure l is a plan View ol' a rollerI rattle guard. constructed in aeoordanee with the invention. Fig. 2 is a l0n gitudinal seeti'onal view on line 2420i Fig@ l. Fig. 3 is a transverse sectional view on line 3-3 of Fig. l. Fig. el. is a detail perspective View of one of the tubular rollers.

`Referring to the drawings l designates a -traine work, which is rectangular in contour, and provided with a pair of transverse bearing beams 2, on 'which the rails 3 are secured. Bet-Ween the rails and the bearing beams, Wear plates 4 are disposed, while on the end beams 5 of the framev l wear plates (3 aresecured. The wear plates 4 and 6 are eoi'istrueted with downturued elongated flanges 7 and S, the purpose oi' which will hereinafter appear.

Specification of Letters tent.

Application led September 30, 1911.

Patented Aug". 26,1 913. semi No. 652,108.

A plurality of tubular rollers 9 are arranged in the frame. The endsoit the rollers, as shown clearly in Fig. 4, are Closed by means of east iron plugs 10, which are annularlyv recessed as shown at 1l, which reeeive the peripheral port-ions ot the tubular rollers. These plugs are secured in position by means of bolts or other suitable means l2. The plugs are provided with steel journal pins 13, which are threaded or otherwise secured in the plug, as shown at'. it. These pins are mounted in bearings 'l5 of the beams Q and 5, as shown in Fig. 3. The down-turned elongated flanges T and S aol; as wear plates tor the pins, for the reason that the beams 2 and 5 are constructed of heavy timber or the like, and the lgiearings l5 therein would become large Jfrom the eonstant movement of the pins in the bearings.

From the foregoing it will be noted, there has been produced a novel, simple and eteient roller cattle guard. and one which has been found to be practicable in Construction and which will prevent cattle -from passing oventhe crossing.

The invention having been set forth, what is claimed as new and useful is:-
